The incorrect statement about denaturation of proteins is
The incorrect statement about denaturation of proteins is
It results due to change of temperature and / or $\mathrm{pH}$
It results in loss of biological activity of proteins.
A protein is formed from amino acids linked by peptide bonds.
Uncoiling of the helical structure takes place.
Solution
Enzymes act at of optimum temperature and pH. Tertiary structure is responsible for biological activities of proteins. With increase in temperature weather $\mathrm{H}$-bond breaks and denaturation occurs resulting in uncoiling of helical structure.
